Hi,
I'm a developer coming from C and I've a question about class
instance as method or function parameter.
In the book "The D Programming Language", I read the instance
was passed by reference to functions (in the opposite of
structures). I understood that it was the same object in the
function and the caller. But I'm think, I was wrong because
when I print the addresses of an object before the function
call and inside the function, they're not the same but the
changes from the function are kept in the instance.
If I use the "ref" qualifier in the function declaration, the 2
addresses are the same.
How do the changes work in the function? Is there a copy ? Or a
"magic" trick :) ?

If you share your code, I'll be happy to take a look. Classes are
reference types, so passing T for a class should pass the
reference to the object.
